ZQJC-160 / 4.4S pneumatic frame pillar drill durable ZQJC-160 / 4.4S pneumatic frame pillar drill latest offer ZQJC-160 / 4.4S pneumatic frame pillar drill is understood, Hunan will resolutely eliminate not have the safety conditions backward production capacity, earnestly implement the coal, non-coal mines, fireworks manufacturers to rectify the closure plan. Where the accident happened over a larger scale in the future following mining and commercial enterprises, ZQJC-160 / 4.4S pneumatic frame pillar drill will be closed in accordance with law. Within five years, no new batch of coal, ZQJC-160 / 4.4S pneumatic frame pillar drill fireworks production and size of the following non-coal mining enterprises. Pneumatic frame pillar drill is designed for high gas concentrations and underground roadway design is not easy to use the power of the machine is the top tight cylinder, with a rotating, driven by a gas motor to the rack and feed back, greatly reducing workers' labor intensity. Change machine is mainly used in the detection of tectonic coal exploration drilling water gas exploration holes, water holes and unloading coal put pressure holes.
